Parts of the martingale collar.
The martingale collar is made up of two loops--the larger of the two is what goes around the dogs neck (loosely adjusted), and the smaller of the two is what is attached to the leash. First, strap the bigger loop loosely around the dog's neck. Then clip the leash to the D ring on the smaller loop.
Martingale collars come in all colors and sizes.
Because of the added parts on the martingale collar, it naturally has more risks involved when keeping it on the dog all the time. Because the loop around the dog's neck tightens when the smaller loop is pulled, never leave the martingale on while the dog is alone at home or in a crate or kennel (the close quarters increases the chance of the collar catching on the side or latch of the crate). If the smaller loop was caught on something, the dog could choke. The smartest idea is to only put the martingale collar on the dog before going outside, according to CollarGirl.com.
